PATENT FRITZ eIAOOBSON, OF BROOKLYN, NEW YORK.

VAPORIZER. 4

SPECIFICATION forming part of Letters Patent No. 691,772, dated January 28, 1902.

Application filed April 15, 1901. Serial No. 55.943. (No model.)

To all whom t may concern:

Be it known that I, FRITZ JAooBsoN, residingin NewYork, borough of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvementsin Vaporizers; and I do hereby declare that the following is a full and clear description thereof.

My invention relates to vaporizers or evaporators.

The improvements constitute a steam vaporizing device. It is more particularly designed for the purpose of evaporatin g or evaporizing medical compounds in order to, distil medicine for the purpose of impregnatin g the air of a room or apartment and at the same time prevent the escape of any watery vapor into the room.

For these purposes my invention consists in the following construction and combinations of parts, the details of which will be first described and the patentable features then set forth and claimed. 1

Figure lrepresents a side elevation of a device embodying my invention. Fig. 2 represents a central vertical section of the same. Fig. 3 is a top plan view.

In the drawings, 1 represents the combustion-chamber, which may be of any suitable dimensions or configuration. This chamber is provided with means for maintainingheat beneath the boiler, such as a lamp 2. Suitable entrances, as perforations 3, may be provided to introduce air to the combustionchamber. The productions of combustion may escape through the annular orifice 4, between the edges of they chamber 1 and the boiler.

4 is the usual door of the combustion-chamber, having an opening covered with a transparency 5.

6 is a water-boiler, preferably supported upon lugs 7 above the combustion-chamber. This boiler is entirely closed to the escape of vapor or steam therefrom except through the safety-valve 7 under undue pressure. Boiler 6 is provided with an opening 8, closed by a cap 9, for the purpose of filling the same with water or other heating media when desired.

10 represents a pair of condensers, preferably supported above the boiler at a suitable distance, as shown. Suitable tubes 11 connect the boiler-space with the condensers.

One of the condensers may be provided with a safety-valve 7, which can be adjustably set to blow o at anyv desired pressure. Other than through the'cap 9 and safety-valve 7 there isno communication with the boiler or condensersV and the outer air. p

,12 is a thermometer-tube supportedby the upper wall of the boiler 6. This tube enters the boiler and passes into the interior of the same, but has no connection with said interior. The tube 12 is adapted to contain an ordinary thermometer, with the thermometerbulb at the lower end. The tube 12 is open at one side, whereby the scale ot' the thermometer may be read within the range of certain degrees essentialfor the proper operation of this Vaporizer.

13 is a depressed annular receptacle formed in the top of the boiler and projecting into the interior thereof. This depression is adapted to hold a basin or receptacle 14, within which the medicine is placed for distillation or vaporization. The depression 13 is deep enough to permit the vessel 14 to be surrounded upon Vits sides and bottom with effective heating-surfaces of the boiler.

In operation the boiler 6 is lilled through the opening S to any proper degree with water. The medicine to be vaporized is placed into thebasin 14. The lamp 2 is lighted. The

Vvapor generated by the heat of the lamp collects in the upper part of the boiler and in the tubes 1l and ccndensers 10. No escape of the steam is permitted unless the pressure generated within the boiler and condenser exceeds the amount for which the safety-val ve is set, when the latter blows off.

In the distillation of medicine for the purpose of impregnating the atmosphereit is essential that the heat generated does not exceed 220 Fahrenheit. Above that temperature, generally speaking, destructive vaporization takes place, which destroys the curative properties of any medicine used for the purpose of air medication. The proper temperature at which effective vaporization of vaporized medical compounds should range is from 200 to 220. The dry vaporiz'ation of medicine, Where the heat is applied directly thereto without the intervention of va transmitting heat medium, like water, is also destructive of the properties of the medicine,

ICO

the inhaling effects of which, in pulmonary diseases especially, are snffoca'ting rather than curative.

Vith the use of my vaporizer I am enabled to apply heat in a beneficial manner by the employment of a fluid agency and at the same time prevent evaporated particles of that agency escaping into the room. In the treatment of consumption it is especially desirable to keep the atmosphere free from all moisture. This result is obtained through the action of the eondensers, Vwhioh'condense the Vapor and return it tothe boiler to be used over again.

The thermometertube,with a thermometer, enables the proper temperature to be maintained, whereby the temperature of the steam generated in the boiler is lkept below the point of destructive distillation of the medi?` cal properties of the medicine and the es-A cape of steam into the room through thebloi off prevented.

If desired, the medicine could be depositeddirectly into the depressed annular portion: 13 of the boiler; but I prefer a separate uten-j sil Aileffor thatpu r pose, in order that the medieine may be more readily prepared and they` vessel more easily kept clean. Instead of lamp I may use any other heating agency,l such as gas, electricity, coal-combustion, bei

being aself-contained article of manufacture. l

What I claim as new, and desire to secure by Letters Patent, is

Ina portable vaporizer apparatus for medicine, thefcombination of a combustion-chamber, a water-chamber above the combustionchamber having a depressed portion in the top thereof, said depressed portion having a fluid-tight connection with Athe Water-chamber, a sealed condenser kabove and separate 'from the water-chamber, a upipe connection between the condenser and the AWater-chamber, athermometer-tube projecting into the Water-chamber and a safety-valve, the whole apparatus being fluid-tight whereby steam is Vprevented from escaping into the room.

In testimony whereof I have affixed my signature inthe presence ofV two Witnesses. y
